Explain. How did changing your independent variable change the way the reaction happened at the particle level.
Your answer should include the following from the evidence:
What is needed to happen between particles for a chemical reaction to occur.
What pattern did you notice when attempting your different trials.
Why did changing your independent variable cause the particles to take a different amount of time to react.

Explain the effects of changing conditions on a reaction at the particle level
Introduction: Chemical reactions are influenced by the conditions of their environment. These components are oftentimes vital to controlling the delicate balance of many existing systems on planet earth. As many ecosystems face challenges such as rising temperatures, acidification, and alternations of nutrient availability, it is important to investigate and identify the driving forces of these changes so that necessary modifications can be made. We have already seen how the ocean is changing and how it is affecting aquatic life such as coral reefs.  In this investigation a chemical reaction will be used as a model to measure how changing conditions can be used to identify drastic shifts occurring in the health of an environmental ecosystem such as the ocean and the many species that live in them.

Instructions: Using Google Sheets and working as a group - organize the experimental data from your investigation into a table and create a graph that can be used for interpretation of patterns and results.

Wash hands with soap and water if skin contact with acid.
Care should be taken when handling or placing acid onto the seashell.
Use a glass stirring rod to stir the liquid; never stir with a thermometer. 
Avoid eating or drinking during the lab - you can poison yourself.
Wash hands thoroughly with soap and water before leaving the laboratory.

Identify how characteristics such as concentration or surface area impact the way that a chemical reaction happens.
Instructions: Prepare for the investigation by using your own knowledge and researching what are the characteristics of a chemical reaction. Identify the variables of your investigation to learn how changing conditions impact what happens to sea shells.

How do the topics discussed in the articles impact individuals, communities, or the world at large?
What are the main environmental concerns and impacts associated with what is happening, as discussed in each article?
How do the articles differ in their focus?
How have the articles expanded your interest and understanding of the relationships between different activities and events around the world?
